Ahead of Caucus, Paul Surges in Iowa

With his popularity among young voters, his consistency on issues, and populist rhetoric about "ending" the Federal Reserve, Paul has formed a broad coalition that has made him the latest front-runner in Iowa. But will it be enough to sustain a national campaign to beat presumptive nominee Mitt Romney?
